“Diabetes” refers to a heterogeneous group of disorders that share impaired glucose intolerance, hyperglycemia, and/or insulin resistance in common. Type I diabetes is characterized by pancreatic endocrine insufficiency or absence; and type II is characterized by insulin resistance. Diabetes refers to disorders in which carbohydrate utilization is reduced; and may be characterized by hyperglycemia, glycosuria, ketoacidosis, neuropathy or nephropathy, increased hepatic glucose production, insulin resistance in various tissues, insufficient insulin secretion and enhanced or poorly controlled glucagon secretion from the pancreas.

Several pathogenic processes are involved in the development of diabetes. These range from autoimmune destruction of the beta-cells of the pancreas with consequent insulin deficiency to abnormalities that result in resistance to insulin action. The basis of the abnormalities in carbohydrate, fat, and protein metabolism in diabetes is deficient action of insulin on target tissues. Deficient insulin action results from inadequate insulin secretion and/or diminished tissue responses to insulin at one or more points in the complex pathways of hormone action. Impairment of insulin secretion and defects in insulin action frequently coexist in the same patient.

Symptoms of marked hyperglycemia include polyuria, polydipsia, weight loss, sometimes with polyphagia, and blurred vision. The vast majority of cases of diabetes fall into two broad etiopathogenetic categories. In one category, type 1 diabetes, the cause is an absolute deficiency of insulin secretion. Individuals at increased risk of developing this type of diabetes can often be identified by serological evidence of an autoimmune pathologic process occurring in the pancreatic islets and by genetic markers. In the other, much more prevalent category, type 2 diabetes, the cause is a combination of resistance to insulin action and an inadequate compensatory insulin secretory response. In the latter category, a degree of hyperglycemia sufficient to cause pathologic and functional changes in various target tissues, but without clinical symptoms, may be present for a long period of time before diabetes is detected. During this asymptomatic period, it is possible to demonstrate an abnormality in carbohydrate metabolism by measurement of plasma glucose in the fasting state or after a challenge with an oral glucose load.

Criteria for the diagnosis of diabetes include:

1. Symptoms of diabetes plus casual plasma glucose concentration 200 mg/dl (11.1 mmol/l). Casual is defined as any time of day without regard to time since last meal. The classic symptoms of diabetes include polyuria, polydipsia, and unexplained weight loss; or 2. Fasting Plasma Glucose equal to or greater than 126 mg/dl (7.0 mmol/l). Fasting is defined as no caloric intake for at least 8 h; or 3. 2-h post-meal or post oral glucose tolerance test (OGTT) glucose concentration of 200 mg/dl (11.1 mmol/l) during an OGTT. The test can be performed as described by WHO, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water.

“Energy expenditure” means basal or resting metabolic rate as defined by Schoeller et al., J Appl Physiol.; 53(4):955-9 (1982). Increases in the resting metabolic rate can be also be measured using increases in O₂ consumption and/or CO₂ efflux and/or increases in organ or body temperature.

“Enhanced oral bioavailability” refers to an increase of at least 50% of the absorption of the dose of the parent drug, unless otherwise specified. In an additional aspect the increase in oral bioavailability of the prodrug (compared to the parent drug) is at least 100% (at least a doubling of the absorption).

(Abstract from AAPS Western Regional Meeting, April, 1997) showed that these alkyloxycarbonyloxymethyl ester prodrugs on (9-[(R)-2-phosphonomethoxy)propyl]adenine (PMPA) are bioavailable up to 30% in dogs.

wherein R^(a) and R^(c) are independently H, alkyl, aryl, alkylaryl, and alicyclic; (see WO 90/08155; WO 90/10636) and R^(b), for e.g., is selected from —OH, —CH₃, —H, —O—CH₃ or monoester prodrug moiety.

Other acyloxyalkyl esters are possible in which a cyclic alkyl ring is formed such as shown in formula B. These esters have been shown to generate phosphorus-containing nucleotides inside cells through a postulated sequence of reactions beginning with deesterification and followed by a series of elimination reactions (e.g., Freed et al., Biochem.

Phenyl as well as mono and poly-substituted phenyl proesters have generated the parent phosphonic acid in studies conducted in animals and in man (Formula C). Another approach has been described where R^(e) is a carboxylic ester ortho to the phosphate (Khamnei et al., J. Med. Chem. 39: 4109-15 (1996)).

wherein R^(e) is 41, alkyl, aryl, alkylaryl, alkoxy, acyloxy, halogen, amino, alkoxycarbonyl, hydroxy, cyano, or heterocycloalkyl and R^(b) is selected, for e.g., from —OH, —CH₃, —H, —O—CH₃ or monoester prodrug moiety.

Benzyl esters have also been reported to generate the parent phosphonic acid. In some cases, using substituents at the para-position can accelerate the hydrolysis. Benzyl analogs with 4-acyloxy or 4-alkyloxy group [Formula D, X═—H, OR or O(CO)R or O(CO)OR] can generate the 4-hydroxy compound more readily through the action of enzymes, e.g., oxidases, esterases, etc. Examples of this class of prodrugs are described in Mitchell et al., J. Chem. Soc. Perkin Trans. 1 2345 (1992); WO 91/19721.

wherein R^(f) and R^(g) are independently —H, alkyl, aryl, alkylaryl, alkoxy, acyloxy, hydroxy, cyano, nitro, perhaloalkyl, halo, or alkyloxycarbonyl; R^(h) is selected, for e.g., from —OH, —CH₃, —H, —O—C₁₋₁₃ or monoester prodrug moiety, as described therein.

R^(h) and R¹ are independently —H, alkyl, aryl, alkylaryl, halogen, or cyclic alkyl.

Thio-containing phosphonate proesters may also be useful in the delivery of drugs to hepatocytes. These proesters contain a protected thioethyl moiety as shown in formula E. One or more of the oxygens of the phosphonate can be esterified. Since the mechanism that results in de-esterification requires the generation of a free thiolate, a variety of thiol protecting groups are possible. For example, the disulfide is reduced by a reductase-mediated process (Puech et al., Antiviral Res. 22: 155-174 (1993)). Thioesters will also generate free thiolates after esterase-mediated hydrolysis Benzaria, et al., J. Med. Chem., 39(25): 4958-65 (1996)). Cyclic analogs are also possible and were shown to liberate phosphonate in isolated rat hepatocytes. The cyclic disulfide shown below has not been previously described and is novel.

wherein R^(j) is alkylcarbonyl, alkoxycarbonyl, arylcarbonyl, aryloxycarbonyl, or alkylthio and R^(b) is selected, for e.g., from —OH, —CH₃, —H, —O—CH₃ or monoester prodrug moiety.

Other examples of suitable prodrugs include proester classes exemplified by Biller and Magnin (U.S. Pat. No. 5,157,027); Serafinowska et al., J. Med. Chem., 38(8): 1372-9 (1995); Starrett et al., J. Med. Chem., 37: 1857 (1994); Martin et al. J. Pharm. Sci. 76: 180 (1987); Alexander et al., Collect. Czech. Chem. Commun, 59: 1853 (1994); and EP 0 632 048 A1. Some of the structural classes described are optionally substituted, including fused lactones attached at the omega position (formulae E4 and E5) and optionally substituted 2-oxo-1,3-dioxolenes attached through a methylene to the phosphorus oxygen (formula E6) such as:

wherein R^(m) is —H, alkyl, cycloalkyl, or heterocycloalkyl; R^(b) is selected, for e.g., from —OH, —CH₃, —H, —O—CH₃ or monoester prodrug moiety and R^(k) is —H, alkyl, aryl, alkylaryl, cyano, alkoxy, acyloxy, halogen, amino, heterocycloalkyl, or alkoxycarbonyl.

The prodrugs of Formula E6 are an example of “optionally substituted heterocycloalkyl where the cyclic moiety contains a carbonate or thiocarbonate.”

Propyl phosphonate proesters can also be used to deliver drugs into hepatocytes. These proesters may contain a hydroxyl and hydroxyl group derivatives at the 3-position of the propyl group as shown in formula F2. The R^(n) and R^(p) groups can form a cyclic ring system as shown in formula F2. One or more of the oxygens of the phosphonate can be esterified.

wherein R^(n) is alkyl, aryl, or heteroaryl;

R^(p) is alkylcarbonyloxy, or alkyloxycarbonyloxy;

R^(b) is selected, for e.g., from —OH, —CH₃, —H, —O—CH₃ or monoester prodrug moiety; and

R^(q) is alkyl, aryl, heteroaryl, alkoxy, alkylamino, alkylthio, halogen,

hydrogen, hydroxy, acyloxy, or amino.

Phosphoramidate derivatives have been explored as phosphate prodrugs (e.g., McGuigan et al., J. Med. Chem., 42: 393 (1999) and references cited therein) as shown in Formula G and H, wherein R^(r), for example, is lower alkyl, lower aryl, lower aralkyl, and as described therein.

Cyclic phosphoramidates have also been studied as phosphonate prodrugs because of their speculated higher stability compared to non-cyclic phosphoramidates (e.g., Starrett et al., J. Med. Chem., 37: 1857 (1994)).

Another type of phosphoramidate prodrug was reported as the combination of S-acyl-2-thioethyl ester and phosphoramidate (Egon et al., Nucleosides & Nucleotides, 18, 981 (1999)) as shown in Formula J wherein R^(c) is alkoxy, aryloxy, alkylthio, arylthio, alkylamino, or arylamino and R^(a) is —H, alkyl, aryl, alkylaryl, or heterocycloalkyl:

Other prodrugs are possible based on literature reports such as substituted ethyls for example, bis(trichloroethyl)esters as disclosed by McGuigan, et al., Bioorg Med. Chem. Lett., 3:1207-1210 (1993), and the phenyl and benzyl combined nucleotide esters reported by Meier. C. et al., Bioorg. Med. Chem. Lett. 7:99-104 (1997).

The structure of formula L has a plane of symmetry running through the phosphorus-oxygen double bond when both R⁶⁰s are the same, V═W, and V and W (defined herein) are either both pointing up or both pointing down. The same is true of structures where both —NR⁶⁰s are replaced with —O—.

The term “cyclic phosphonate ester of 1,3-propane diol”, “cyclic phosphonate diester of 1,3-propane diol”, “2 oxo 2λ^(5 [)1,3,2]dioxaphosphonane”, “2 oxo[1,3,2]dioxaphosphonane”, “dioxaphosphonane” refers to the following:

The structure shown above (left) has an additional 3 carbon atoms that forms a five member cyclic group. Such cyclic groups must possess the listed substitution to be oxidized.

The phrase “together V and Z are connected via an additional 3-5 atoms to form a cyclic group, optionally containing one heteroatom, that is fused to an aryl group attached at the beta and gamma position to the G attached to the phosphorus” includes the following:

The structure above has an acyloxy substituent that is three carbon atoms from a Y, and an optional substituent, —CH₃, on the new 6-membered ring. There has to be at least one hydrogen at each of the following positions: the carbon attached to Z; both carbons alpha to the carbon labeled “3”; and the carbon attached to “OC(O)CH₁” above.

The phrase “together W and W′ are connected via an additional 2-5 atoms to form a cyclic group, optionally containing 0-2 heteroatoms, and V must be aryl, substituted aryl, heteroaryl, or substituted heteroaryl” includes the following:

The structure above has V=aryl, and a spiro-fused cyclopropyl group for W and W.

The term “cyclic phosphon(amid)ate” refers to:

${\frac{\lbrack R\rbrack - \lbrack S\rbrack}{\lbrack R\rbrack + \lbrack S\rbrack} \times 100} = {{\% \mspace{14mu} R} - {\% \mspace{14mu} S}}$

where [R] is the amount of the R isomer and [S] is the amount of the S isomer. This formula provides the % ee when R is the dominant isomer.

The term “enantioenriched” or “enantiomerically enriched” refers to a sample of a chiral compound that consists of more of one enantiomer than the other. The extent to which a sample is enantiomerically enriched is quantitated by the enantiomeric ratio or the enantiomeric excess.

Compounds and Uses Thereof:

The enzyme glucokinase plays a critical role in the regulation of blood glucose levels. It is expressed in a restricted number of cell types, most notably the pancreatic beta-cell and liver parenchymal cells. Glucokinase catalyzes the rate-limiting step in glucose uptake, metabolism (glycolysis), and glucose storage (glycogenesis) in cells. In pancreatic beta cells, glucose uptake and metabolism trigger insulin secretion. Glucokinase is often referred to as a “glucose sensor” since it matches the rate of insulin secretion by pancreatic beta cells as well as the rate of glucose metabolism by liver cells to the ambient glucose concentrations.

Recent clinical data on pharmacological agents that simultaneously activate glucokinase in the pancreas and the liver have revealed a high rate of the undesirable side effect of hypoglycemia in treated patients. Development of this potentially lethal condition is attributed to the potent stimulation of insulin secretion. Compounds of the current invention were designed to safely lower blood glucose by selectively targeting glucokinase expressed in liver and thereby avoiding the activation of glucokinase in the pancreas. Treatment of diabetic rodents with compounds of the current invention resulted in significant blood glucose lowering without an increase in insulin secretion. Importantly, treatment with these agents did not result in hypoglycemia. In parallel studies with an activator of both pancreatic and hepatic glucokinase, treatment was associated with insulin secretion and a reduction of blood glucose below normal levels, i.e., hypoglycemia. Long term stimulation of insulin secretion is known to lead to pancreatic failure and an exacerbation of the diabetic condition as observed with the sulfonylurea drug class. Compounds of the current invention, by selectively targeting the liver, also provide a safe mechanism of glucose lowering that avoids insulin secretion, hypoglycemia, and pancreatic burnout.

These excipients may be, for example, inert diluents, such as calcium or sodium carbonate, lactose, calcium or sodium phosphate; granulating and disintegrating agents, such as maize starch, or alginic acid; binding agents, such as starch, gelatin or acacia; and lubricating agents, such as magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by known techniques including microencapsulation to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. One aspect relates to the administration of a pharmaceutically acceptable composition of the present invention by controlled- or delayed-release means. Controlled-release pharmaceutical products have a common goal of improving drug therapy over that achieved by their non-controlled release counterparts.

A variety of known controlled- or extended-release dosage forms, formulations, and devices can be adapted for use with the crystalline forms of the invention. Examples include, but are not limited to, those described in U.S. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 3,598,123; 4,008,719; 5,674,533; 5,059,595; 5,591,767; 5,120,548; 5,073,543; 5,639,476; 5,354,556; 5,733,566; and 6,365,185; each of which is incorporated herein by reference.

These dosage forms can be used to provide delayed or controlled-release of one or more active ingredients using, for example, hydroxypropylmethyl cellulose, other polymer matrices, gels, permeable membranes, osmotic systems (such as OROS, Alza Corporation, Mountain View, Calif. USA), multilayer coatings, microparticles, liposomes, or microspheres or a combination thereof to provide the desired release profile in varying proportions. Additionally, ion exchange materials can be used to prepare immobilized, adsorbed co-crystals and thus effect controlled delivery of the drug. Examples of specific anion exchangers include, but are not limited to, Duolite A568 and Duolite AP143 (Rohm & Haas, Spring House, Pa., USA).

One aspect of the invention encompasses a unit dosage form which comprises a pharmaceutically acceptable composition comprising a crystalline form of a compound of the present invention and one or more pharmaceutically acceptable excipients or diluents, wherein the pharmaceutical composition, medicament or dosage forms is formulated for controlled-release. In another aspect, the dosage form utilizes an osmotic drug delivery system.

A particular and well-known osmotic drug delivery system is referred to as OROS (Alza Corporation, Mountain View, Calif. USA). This technology can readily be adapted for the delivery of compounds and compositions of the invention. Various aspects of the technology are disclosed in U.S. Pat. Nos. 6,375,978; 6,368,626; 6,342,249; 6,333,050; 6,287,295; 6,283,953; 6,270,787; 6,245,357; and 6,132,420; each of which is incorporated herein by reference. Specific adaptations of OROS that can be used to administer compounds and compositions of the invention include, but are not limited to, the OROS; Push-Pull, Delayed Push-Pull, Multi-Layer Push-Pull, and Push-Stick Systems, all of which are well known. See, e.g., www alza.com. Additional OROS systems that can be used for the controlled oral delivery of compounds and compositions of the invention include OROS-CT and L-OROS (Id.; see also, Delivery Times, vol. II, issue II (Alza Corporation).

Conventional OROS oral dosage forms are made by compressing a drug powder (e.g. a crystalline form selected from Forms A-D) into a hard tablet, coating the tablet with cellulose derivatives to form a semi-permeable membrane, and then drilling an orifice in the coating (e.g., with a laser). Kim, Cherug-ju, Controlled Release Dosage Form Design, 231-238 (Technomic Publishing, Lancaster, Pa.: 2000). The advantage of such dosage forms is that the delivery rate of the drug is not influenced by physiological or experimental conditions. Even a drug with a pH-dependent solubility can be delivered at a constant rate regardless of the pH of the delivery medium. But because these advantages are provided by a build-up of osmotic pressure within the dosage form after administration, conventional OROS drug delivery systems cannot be used to effectively deliver drugs with low water solubility. Id. at 234.

A specific dosage form of the invention comprises: a wall defining a cavity, the wall having an exit orifice formed or formable therein and at least a portion of the wall being semipermeable; an expandable layer located within the cavity remote from the exit orifice and in fluid communication with the semipermeable portion of the wall; a dry or substantially dry state drug layer located within the cavity adjacent to the exit orifice and in direct or indirect contacting relationship with the expandable layer; and a flow-promoting layer interposed between the inner surface of the wall and at least the external surface of the drug layer located within the cavity, wherein the drug layer comprises a crystalline form of a compound of the present invention. See U.S. Pat. No. 6,368,626, the entirety of which is incorporated herein by reference.

Another specific dosage form of the invention comprises: a wall defining a cavity, the wall having an exit orifice formed or formable therein and at least a portion of the wall being semipermeable; an expandable layer located within the cavity remote from the exit orifice and in fluid communication with the semipermeable portion of the wall; a drug layer located within the cavity adjacent the exit orifice and in direct or indirect contacting relationship with the expandable layer; the drug layer comprising a liquid, active agent formulation absorbed in porous particles, the porous particles being adapted to resist compaction forces sufficient to form a compacted drug layer without significant exudation of the liquid, active agent formulation, the dosage form optionally having a placebo layer between the exit orifice and the drug layer, wherein the active agent formulation comprises a crystalline form of a compound of the present invention. See U.S. Pat. No. 6,342,249, the entirety of which is incorporated herein by reference.

In another aspect, a pharmaceutical composition or medicament comprising a crystalline form of a compound of the present invention is administered transdermally. Such a transdermal (TD) delivery can avoid first-pass metabolism. Additionally, a “pill-and-patch” strategy can be taken, where only a fraction of the daily dose is delivered through the skin to generate basal systemic levels, onto which oral therapy is added.

Formulations for oral use may be also presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin or olive oil.

Aqueous suspensions of the invention contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients include a suspending agent, such as sodium carboxymethylcellulose, methylcellulose, ethylcellulose, hydroxypropylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as a naturally occurring phosphatide (e.g., lecithin), a condensation product of an alkylene oxide with a fatty acid (e.g., polyoxyethylene stearate), a condensation product of ethylene oxide with a long chain aliphatic alcohol (e.g., heptadecaethyleneoxycetanol), a condensation product of ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride (e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension may also contain one or more preservatives such as ethyl or n-propyl p-hydroxy-benzoate, one or more coloring agents, one or more flavoring agents and one or more sweetening agents, such as sucrose or saccharin.

Oil suspensions may be formulated by suspending the active ingredient in a vegetable oil, such as arachid oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oral suspensions may contain a thickening agent, such as beeswax, hard paraffin or cetyl alcohol. Sweetening agents, such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid.

Dispersible powders and granules of the invention suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent, and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those disclosed above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present.

The pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, such as olive oil or arachid oil, a mineral oil, such as liquid paraffin, or a mixture of these. Suitable emulsifying agents include naturally-occurring gums, such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan monooleate, and condensation products of these partial esters with ethylene oxide, such as polyoxyethylene sorbitan monooleate. The emulsion may also contain sweetening and flavoring agents.

Syrups and elixirs may be formulated with sweetening agents, such as glycerol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative, a flavoring or a coloring agent.

The pharmaceutical compositions of the invention may be in the form of a sterile injectable preparation, such as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, such as a solution in 1,3-butane-diol or prepared as a lyophilized powder. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile fixed oils may conventionally be employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may likewise be used in the preparation of injectables.

As noted above, formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous or non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be administered as a bolus, electuary or paste.

A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free flowing form such as a powder or granules, optionally mixed with a binder (e.g., povidone, gelatin, hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (e.g., sodium starch glycolate, cross-linked povidone, cross-linked sodium carboxymethyl cellulose) surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. The tablets may optionally be coated or scored and may be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropyl methylcellulose in varying proportions to provide the desired release profile. Tablets may optionally be provided with an enteric coating, to provide release in parts of the gut other than the stomach. This is particularly advantageous with the compounds of Formula I when such compounds are susceptible to acid hydrolysis.

Formulations suitable for topical administration in the mouth include lozenges comprising the active ingredient in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin, or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

Formulations for rectal administration may be presented as a suppository with a suitable base comprising for example cocoa butter or a salicylate.

Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or spray formulations containing in addition to the active ingredient such carriers as are known in the art to be appropriate.

Formulations suitable for parenteral administration include aqueous and non-aqueous isotonic sterile injection solutions which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. The formulations may be presented in unit-dose or multi-dose sealed containers, for example, ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.

Formulations suitable for parenteral administration may be administered in a continuous infusion manner via an indwelling pump or via a hospital bag.

The infusions may be done through a Hickman or PICC or any other suitable means of administering a formulation either parenterally or i.v.

Preferred unit dosage formulations are those containing a daily dose or unit, daily sub-dose, or an appropriate fraction thereof, of a drug.

It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed; the age, body weight, general health, sex and diet of the individual being treated; the time and route of administration; the rate of excretion; other drugs which have previously been administered; and the severity of the particular disease undergoing therapy, as is well understood by those skilled in the art.

EXAMPLES Synthesis of Compounds of the Invention

Compounds of Formula I and Formula II can be prepared according to the methodology outlined in the following general synthetic schemes or with modifications of these schemes that will be evident to persons skilled in the art.

Synthesis of the Phosphonate Prodrug Compounds of the Invention 1) Preparation of a Phosphonate Prodrug

Prodrugs can be introduced at different stages of the synthesis. Most often these prodrugs are made from the phosphonic acids of compounds of the invention because of their lability. Phosphonic acids of compounds of the invention can be alkylated with electrophiles such as alkyl halides and alkyl sulfonates under nucleophilic substitution conditions to give phosphonate esters. For example, acyloxyalkyl prodrugs of compounds of the invention can be prepared by direct alkylation of compounds of Formula I with an appropriate acyloxyalkyl halide (e.g., Cl, Br, I; Phosphorus Sulfur 54:143 (1990); Synthesis 62 (1988)) in the presence of a suitable base (e.g., pyridine, TEA, diisopropylethylamine) in suitable solvents such as DMF (J. Med. Chem. 37:1875 (1994)). The carboxylate component of these acyloxyalkyl halides includes but is not limited to acetate, propionate, isobutyrate, pivalate, benzoate, carbonate and other carboxylates.

Dimethylformamide dialkyl acetals can also be used for the alkylation of phosphonic acids (Collect. Czech Chem. Commu. 59:1853 (1994)). Compounds of the invention wherein the prodrug moiety comprises a cyclic carbonate, a lactone or a phthalidyl group can also be synthesized by direct alkylation of the free phosphonic acids with appropriate halides in the presence of a suitable base such as NaH or diisopropylethylamine (J. Med. Chem. 38:1372 (1995); J. Med. Chem. 37:1857 (1994); J. Pharm. Sci. 76:180 (1987)).

Alternatively, these phosphonate prodrugs can be synthesized by the reactions of the corresponding dichlorophosphonates and an alcohol (Collect Czech Chem. Commun. 59:1853 (1994)). For example, a dichlorophosphonate is reacted with substituted phenols and arylalkyl alcohols in the presence of a base such as pyridine or TEA to give the compounds of the invention wherein the prodrug moiety is an aryl group (J. Med. Chem. 39:4109 (1996); J. Med. Chem. 38:1372 (1995); J. Med. Chem. 37:498 (1994)) or an arylalkyl group (J. Chem. Soc. Perkin Trans. 138:2345 (1992)). The disulfide-containing prodrugs (Antiviral Res. 22:155 (1993)) can be prepared from a dichlorophosphonate and 2-hydroxyethyldisulfide under standard conditions. Dichlorophosphonates are also useful for the preparation of various phosphonamides as prodrugs. For example, treatment of a dichlorophosphonate with ammonia gives both a monophosphonamide and a diphosphonamide; treatment of a dichlorophosphonate with 1-amino-3-propanol gives a cyclic 1,3-propylphosphonamide; treatment of a chlorophosphonate monophenyl ester with an amino acid ester in the presence of a suitable base gives a substituted monophenyl monophosphonamidate.

Such reactive dichlorophosphonates can be generated from the corresponding phosphonic acids with a chlorinating agent (e.g., thionyl chloride, J. Med. Chem. 1857 (1994); oxalyl chloride, Tetrahedron Lett. 31:3261 (1990); phosphorous pentachloride, Synthesis 490 (1974)). Alternatively, a dichlorophosphonate can be generated from its corresponding disilyl phosphonate esters (Synth. Commu. 17:1071 (1987)) or dialkyl phosphonate esters (Tetrahedron Lett. 24:4405 (1983); Bull. Soc. Chim. 130:485 (1993)). Compounds of the invention can be mixed phosphonate ester (e.g., phenyl and benzyl esters, or phenyl and acyloxyalkyl esters) including the chemically combined mixed esters such as phenyl and benzyl combined prodrugs reported in Bioorg. Med. Chem. Lett. 7:99 (1997).

Dichlorophosphonates are also useful for the preparation of various phosphonamides as prodrugs. For example, treatment of a dichlorophosphonate with an amine (e.g. an amino acid alkyl ester such as L-alanine ethyl ester) in the presence of a suitable base (e.g. triethylamine, pyridine, etc.) gives the corresponding bisphosphonamide; treatment of a dichlorophosphonate with 1-amino-3-propanol gives a cyclic 1,3-propylphosphonamide; treatment of a chlorophosphonate monophenyl ester with an amino acid ester in the presence of a suitable base gives a substituted monophenyl monophosphonamidate. Direct couplings of a phosphonic acid with an amine (e.g. an amino acid alkyl ester such as L-alanine ethyl ester) are also reported to give the corresponding bisamidates under Mukaiyama conditions (J. Am. Chem. Soc., 94:8528 (1972)).

The SATE (S-acetyl thioethyl) prodrugs can be synthesized by the coupling reaction of the phosphonic acid compounds of the invention and S-acyl-2-thioethanol in the presence of DCC, EDCI or PyBOP (J. Med. Chem. 39:1981 (1996)).

Cyclic phosphonate esters of substituted 1,3-propane diols can be synthesized by either reactions of the corresponding dichlorophosphonate with a substituted 1,3-propanediol or coupling reactions using suitable coupling reagents (e.g., DCC, EDCI, PyBOP; Synthesis 62 (1988)). The reactive dichlorophosphonate intermediates can be prepared from the corresponding acids and chlorinating agents such as thionyl chloride (J. Med. Chem. 1857 (1994)), oxalyl chloride (Tetrahedron Lett. 31:3261 (1990)) and phosphorus pentachloride (Synthesis 490 (1974)). Alternatively, these dichlorophosphonates can also be generated from disilyl esters (Synth. Commun. 17:1071 (1987)) and dialkyl esters (Tetrahedron Lett. 24:4405 (1983); Bull. Soc. Chim. Fr, 130:485 (1993)).

Alternatively, these cyclic phosphonate esters of substituted 1,3-propane diols are prepared from phosphonic acids by coupling with diols under Mitsunobu reaction conditions (Synthesis 1 (1981); J. Org. Chem. 52:6331 (1992)), and other acid coupling reagents including, but not limited to, carbodiimides (Collect. Czech. Chem. Commun. 59:1853 (1994); Bioorg. Med. Chem. Lett. 2:145 (1992); Tetrahedron Lett. 29:1189 (1988)), and benzotriazolyloxytris-(dimethylamino) phosphonium salts (Tetrahedron Lett. 34:6743 (1993)).

Phosphonic acids also undergo cyclic prodrug formation with cyclic acetals or cyclic ortho esters of substituted propane-1,3-diols to provide prodrugs as in the case of carboxylic acid esters (Helv. Chim. Acta. 48:1746 (1965)). Alternatively, more reactive cyclic sulfites or sulfates are also suitable coupling precursors to react with phosphonic acid salts. These precursors can be made from the corresponding diols as described in the literature.

Alternatively, cyclic phosphonate esters of substituted 1,3-propane diols can be synthesized by trans esterification reaction with substituted 1,3-propane diol under suitable conditions. Mixed anhydrides of parent phosphonic acids generated in situ under appropriate conditions react with diols to give prodrugs as in the case of carboxylic acid esters (Bull. Chem. Soc. Jpn. 52:1989 (1979)). Aryl esters of phosphonates are also known to undergo transesterification with alkoxy intermediates (Tetrahedron Lett. 38:2597 (1997); Synthesis 968 (1993)).

One aspect of the present invention provides methods to synthesize and isolate single isomers of prodrugs of compounds of the invention that are phosphoric acids. Because phosphorus is a stereogenic atom, formation of a prodrug with a substituted-1,3-propane-diol will produce a mixture of isomers. For example, formation of a prodrug with a racemic 1-(V)-substituted-1,3-propane diol gives a racemic mixture of cis-prodrugs and a racemic mixture of trans-prodrugs. In an other aspect, the use of the enantioenriched substituted-1,3-propane diol with the R-configuration gives enantioenriched R-cis- and R-trans-prodrugs. These compounds can be separated by a combination of column chromatography and/or fractional crystallization.

The compounds of the invention can be mixed phosphonate esters (e.g. phenyl benzyl phosphonate esters, phenyl acyloxyalkyl phosphonate esters, phenyl aminoacid esters etc). For example, the chemically combined phenyl-benzyl prodrugs are reported by Meier, et Bioorg. Med. Chem. Lett., 1997, 7: 99.

The substituted cyclic propyl phosphonate esters compounds of the invention, can be synthesized by reaction of the corresponding dichlorophosphonate and the substituted 1,3-propane diol. The following are non-limiting methods to prepare the substituted 1,3-propane diols.

Synthesis of the 1,3-Propane Diols Used in the Preparation of Certain Prodrugs

The discussion of this step includes various synthetic methods for the preparation of the following types of propane-1,3-diols: i) 1-substituted; ii) 2-substituted; and iii) 1,2- or 1,3-annulated. Different groups on the prodrug part of the molecule i.e., on the propane diol moiety can be introduced or modified either during the synthesis of the diols or after the synthesis of the prodrugs.

i) 1-Substituted 1,3-Propanediols

1,3-Propanediols useful in the synthesis of compounds in the present invention can be prepared using various synthetic methods. As described in Scheme A, additions of an aryl Grignard to a 1-hydroxy-propan-3-al give 1-aryl-substituted 1,3-propanediols (path a). This method is suitable for the conversion of various aryl halides to 1-arylsubstituted-1,3-propanediols (J. Org. Chem. 1988, 53, 911). Conversions of aryl halides to 1-substituted 1,3-propanediols can also be achieved using Heck reactions (e.g., couplings with a 1,3-diox-4-ene) followed by reductions and subsequent hydrolysis reactions (Tetrahedron Lett. 1992, 33, 6845). Various aromatic aldehydes can also be converted to 1-substituted-1,3-propanediols using alkenyl Grignard addition reactions followed by hydroboration-oxidation reactions (path b).

Aldol reactions between an enolate (e.g., lithium, boron, tin enolates) of a carboxylic acid derivative (e.g., tert-butyl acetate) and an aldehyde (e.g., the Evans's aldol reactions) are especially useful for the asymmetric synthesis of enantioenriched 1,3-propanediols. For example, reaction of a metal enolate off-butyl acetate with an aromatic aldehyde followed by reduction of the ester (path e) gives a 1,3-propanediol (J. Org. Chem. 1990, 55 4744). Alternatively, epoxidation of cinnamyl alcohols using known methods (e.g., Sharpless epoxidations and other asymmetric epoxidation reactions) followed by reduction reactions (e.g., using Red-Al) give various 1,3-propanediols (path c). Enantioenriched 1,3-propanediols can be obtained via asymmetric reduction reactions (e.g., enantioselective borane reductions) of 3-hydroxy-ketones (Tetrahedron Lett. 1997, 38 761). Alternatively, resolution of racemic 1,3-propanediols using various methods (e.g., enzymatic or chemical methods) can also give enantioenriched 1,3-propanediol. Propan-3-ols with a 1-heteroaryl substituent (e.g., a pyridyl, a quinolinyl or an isoquinolinyl) can be oxygenated to give 1-substituted 1,3-propanediols using N-oxide formation reactions followed by a rearrangement reaction in acetic anhydride conditions (path d) (Tetrahedron 1981, 37, 1871).

ii) 2-Substituted 1,3-Propanediols

A variety of 2-substituted 1,3-propanediols useful for the synthesis of compounds of Formula I can be prepared from various other 1,3-propanediols (e.g., 2-(hydroxymethyl)-1,3-propanediols) using conventional chemistry (Comprehensive Organic Transformations, VCH, New York, 1989). For example, as described in Scheme B. reductions of a trialkoxycarbonylmethane under known conditions give a triol via complete reduction (path a) or a bis(hydroxymethyl)acetic acid via selective hydrolysis of one of the ester groups followed by reduction of the remaining two other ester groups. Nitrotriols are also known to give triols via reductive elimination (path b) (Synthesis 1987, 8, 742). Furthermore, a 2-(hydroxymethyl)-1,3-propanediol can be converted to a mono acylated derivative (e.g., acetyl, methoxycarbonyl) using an acyl chloride or an alkyl chloroformate (e.g., acetyl chloride or methyl chloroformate) (path d) using known chemistry (Protective Groups In Organic Synthesis; Wiley, New York, 1990). Other functional group manipulations can also be used to prepare 1,3-propanediols such as oxidation of one the hydroxymethyl groups in a 2-(hydroxymethyl)-1,3-propanediol to an aldehyde followed by addition reactions with an aryl Grignard (path c). Aldehydes can also be converted to alkyl amines via reductive amination reactions (path e).

iii) Annulated 1,3-Propane Diols

Compounds of invention wherein V and Z or V and W are connected by four carbons to form a ring can be prepared from a 1,3-cyclohexanediol. For example, cis, cis-1,3,5-cyclohexanetriol can be modified to give various other 1,3,5-cyclohexanetriols which are useful for the preparations of compounds of Formula I wherein R⁵¹ and R⁵¹ together are

wherein together V and W are connected via 3 atoms to form a cyclic group containing 6 carbon atoms substituted with a hydroxy group. It is envisioned that these modifications can be performed either before or after formation of a cyclic phosphonate 1,3-propanediol ester. Various 1,3-cyclohexanediols can also be prepared using Diels-Alder reactions (e.g., using a pyrone as the diene: Tetrahedron Lett. 1991, 32, 5295). 2-Hydroxymethylcyclohexanols and 2-hydroxymethylcyclopentanols are useful for the preparations of compounds of the invention wherein R⁵¹ and R⁵¹ together are

wherein together V and Z are connected via 2 or 3 atoms to form a cyclic group containing 5 or 6 carbon atoms. 1,3-Cyclohexanediol derivatives are also prepared via other cycloaddition reaction methodologies. For example, cycloadducts from the cycloadditon reactions of a nitrile oxide and an olefin can be converted to a 2-ketoethanol derivative which can be further converted to a 1,3-propanediol (including-1,3-cyclohexanediol, 2-hydroxymethylcyclohexanol and 2-hydroxymethylcyclopentanol) using known chemistry (J. Am. Chem. Soc. 1985, 107. 6023). Alternatively, precursors to 1,3-cyclohexanediol can be made from quinic acid (Tetrahedron Lett. 1991, 32, 547.)

Generation of Phosphonic Acid

Select compounds may be prepared from phosphonate esters using known phosphate and phosphonate ester cleavage conditions. In general, silyl halides have been used to cleave the various phosphonate esters, followed by mild hydrolysis of the resulting silyl phosphonate esters to give the desired phosphonic acids. Depending on the stability of the products, these reactions are usually accomplished in the presence of acid scavengers such as 1,1,1,3,3,3-hexamethyldisilazane, 2,6-lutidine, etc. Such silyl halides include, chlorotrimethylsilane (Rabinowitz, J. Org. Chem., 1963, 28: 2975), bromotrimethylsilane (McKenna, et al, Tetrahedron Lett., 1977, 155), iodotrimethylsilane (Blackburn, et al, J. Chem. Soc., Chem. Commun., 1978, 870). Alternately, phosphonate esters can be cleaved under strong acid conditions, (e.g HBr, HCl, etc.) in polar solvents, preferably acetic acid (Moffatt, et al, U.S. Pat. No. 3,524,846, 1970) or water. These esters can also be cleaved via dichlorophosphonates, prepared by treating the esters with halogenating agents e.g. phosphorus pentachloride, thionyl chloride, BBr₃, etc. (Pelchowicz, et al, J. Chem. Soc., 1961, 238) followed by aqueous hydrolysis to give phosphonic acids. Aryl and benzyl phosphonate esters can be cleaved under hydrogenolysis conditions (Lejczak, et al, Synthesis, 1982, 412; Elliott, et al, J. Med. Chem., 1985, 28: 1208; Baddiley, et al, Nature, 1953, 171: 76) or dissolving metal reduction conditions (Shafer, et al, J. Am. Chem. Soc., 1977, 99: 5118). Electrochemical (Shono, et al, J. Org. Chem., 1979, 44: 4508) and pyrolysis (Gupta, et al, Synth. Commun., 1980, 10: 299) conditions have also been used to cleave various phosphonate esters.

Synthesis of the Phosphinate and Phosphonate Monoester Prodrug Compounds of the Invention 1) Preparation of Phosphinate and Phosphonate Monoester Prodrug

Phosphinic acids and phosphonic acid monoesters can be alkylated with electrophiles such as alkyl halides and alkyl sulfonates under nucleophilic substitution conditions to give phosphinate and phosphonate ester prodrugs. For example, compounds of Formulas I and II wherein Y²R⁵¹ is an acyloxyalkyl group can be prepared by direct alkylation of compounds of Formulas I and II wherein Y²R⁵¹ is OH with an appropriate acyloxyalkyl halide (e.g., Cl, Br, I; Phosphorus Sulfur 54:143 (1990); Synthesis 62 (1988)) in the presence of a suitable base (e.g., pyridine, TEA, diisopropylethylamine) in suitable solvents such as DMF (J. Med. Chem. 37:1875 (1994)). The carboxylate component of these acyloxyalkyl halides includes but is not limited to acetate, propionate, isobutyrate, pivalate, benzoate, carbonate and other carboxylates.

Dimethylformamide dialkyl acetals can also be used for the alkylation of phosphinic acids and phosphonic acid monoesters (Collect. Czech Chem. Commu. 59:1853 (1994)). Compounds of Formulas I and II wherein Y²R⁵¹ is a cyclic carbonate, a lactone or a phthalidyl group can also be synthesized by direct alkylation of the free phosphonic acids with appropriate halides in the presence of a suitable base such as NaH or diisopropylethylamine (J. Med. Chem. 38:1372 (1995); J. Med. Chem. 37:1857 (1994); J. Pharm. Sci. 76:180 (1987)).

Alternatively, these phosphinate and phosphonate monoester prodrugs can be synthesized by the reactions of the corresponding chlorophospho(i)nate and an alcohol (Collect Czech Chem. Commun. 59:1853 (1994)). For example, a chlorophospho(i)nate is reacted with substituted phenols and arylalkyl alcohols in the presence of a base such as pyridine or TEA to give the compounds of Formula I wherein YR⁵¹ is an aryl group (J. Med. Chem. 39:4109 (1996); J. Med. Chem. 38:1372 (1995); J. Med. Chem. 37:498 (1994)) or an arylalkyl group (J. Chem. Soc. Perkin Trans. 1 38:2345 (1992)). The disulfide-containing prodrugs (Antiviral Res. 22:155 (1993)) can be prepared from a chlorophospho(i)nate and 2-hydroxyethyldisulfide under standard conditions. Chlorophospho(i)nates are also useful for the preparation of various phospho(i)namides as prodrugs. For example, treatment of a chlorophospho(i)nate with ammonia gives the phospho(i)namide.

Such reactive chlorophospho(i)nates can be generated from the corresponding phosphinic acids and phosphonic acid monoesters with a chlorinating agent (e.g., thionyl chloride, J. Med. Chem. 1857 (1994); oxalyl chloride, Tetrahedron Lett. 31:3261 (1990); phosphorous pentachloride, Synthesis 490 (1974)). Alternatively, a chlorophospho(i)nate can be generated from its corresponding silyl phosphinate ester or phosphonic acid monester (Synth. Commu. 17:1071 (1987)) or alkyl phosphinate esters (Tetrahedron Lett. 24:4405 (1983); Bull. Soc. Chim. 130:485 (1993)).

Chlorophospho(i)nates are also useful for the preparation of various phosphonamides as prodrugs. For example, treatment of a chlorophospho(i)nate with an amine (e.g. an amino acid alkyl ester such as L-alanine ethyl ester) in the presence of a suitable base (e.g. triethylamine, pyridine, etc.) gives the corresponding phospho(i)namide. Direct couplings of phosphinic acids or phosphonic acid monoesters with an amine (e.g. an amino acid alkyl ester such as L-alanine ethyl ester) are also reported to give the corresponding amidate under Mukaiyama conditions (J. Am. Chem. Soc. 94:8528 (1972)).

The SATE (S-acetyl thioethyl) prodrugs can be synthesized by the coupling reaction of the phosphinic acids or phosphonic acid monoesters of Formulas I and II and S-acyl-2-thioethanol in the presence of DCC, EDCI or PyBOP (J. Med. Chem. 39:1981 (1996)).

2) Generation of Phosphonic Acid Monoesters

Compounds of Formulas I and II wherein R⁵⁰ is —P(O)(Y²R⁵¹)(OR³) and R³ is C₁-C₆alkyl may be prepared from the diester intermediate, used for the synthesis of phosphonic acid, by monosaponification. Monohydrolysis of one of the ester groups on the phosphonate may be accomplished by treatment of phosphonate diesters with aqueous alkaline solution such as NaOH, KOH or LiOH at rt or while heating. Sodium azide can also be used in DMF (Bioorg. Med. Chem. Lett. 14(13), 3559-62 (2004)) to accomplished the monosaponification. Alternatively, organic bases such as morpholine or N-methyl-piperazine can be used to hydrolyze one of the phosphonate ester groups (Synth. Comm. 34(2):331-344 (2004)).

3) Generation of Phosphinic Acids

The introduction of a phosphinic acid group can generally be accomplished according to known methods. An efficient way to synthesize phosphinic acid is to convert a phosphonate diester to its corresponding monochloridate-monoester using one of many chlorinating agents such as PCl₅ (Can. J. Chem. 76(3):313-18 (1998)), oxalyl chloride (Tetrahedron Lett. 44(12):1445-48 (2003)), thionyl chloride (J. Med. Chem. 45(4):919-29 (2002)) or phosgene (Recl. Trav. Chim. Pays-Bas 78:59-61 (1959)) and to introduce the carbon-based substituent on the phosphorus atom via a Grignard reagent (J. Chem. Soc. Perkin Trans. 1 17:2179-86 (1996)), a lithium anion (J. Med. Chem. 33(11):2952-56 (1990)) or an enolate (Bioorg Med. Chem. 5(7):1327-38 (1997)) to produce the desired phosphinate ester. The phosphinic acid is then generated by saponification with aqueous NaOH, KOH or LiOH or using one of the many methods known to deprotect phosphonic acids such as TMSBr or TMSCl/KI. Alternatively, phosphinic acids can be generated from phosphonic acid monoesters by making the monochloridate-monoester with chlorinating reagents such as thionyl chloride or oxalyl chloride, and introducing the substituent on the phosphorus as above.

Other methods include palladium-catalyzed cross-coupling of alkyl phosphinates to form H-phosphinate esters (Tetrahedron 61(26):6315-6329 (2005)), based-promoted alkylation of H-phosphinate esters with electrophiles (J. Org. Chem. 72(8):2851-2856 (2007)), and palladium-catalyzed cross-coupling of (low alkyl)phosphinic acid ester with aryl halides and aryl triflates (J. Org. Chem. 63(10):3463-3467 (1998); Synthesis (14):2216-2220 (2003); Synthesis (9):778-780 (1984)).

Cyclic phosphinic acids can be synthesized starting from a 1,2-dicarboxylate-benzene precursor (J. Am. Chem. Soc. 101:7001-08 (1979)) which is reduced to the di-benzylic alcohol and brominated with PBr₃ to give the di-benzylic bromide precursor (Synth. Commun. 14(6):507-514 (1984)). Double Arbuzov condensation of the di-benzylic bromide with bis(trimethylsilyloxy)phosphine, made from the reaction of ammonium hypophosphite and hexamethyldisilazane, provides the cyclic phosphinate ester (J. Org. Chem. 60:6076-81 (1995)) which can be converted to the phosphinic acid by saponification with NaOH or TMSBr. Alternatively, the di-benzyl bromide precursor can be obtained by bromination of a substituted 1,2-dimethyl benzene with bromine or N-bromosuccinimide (J. Chem. Soc. 3358-61 (1959)) or direct bromomethylation by reacting formaldehyde and HBr in presence of acetic acid (J. Phys. Chem. 108(4):5145-55 (2004)).

The following examples are provided so that the invention can be more fully understood and should not be construed as limiting the invention in any way.

Hydrogen atoms on both carbon and heteroatoms may be implied on chemical structures within.

EXAMPLES Synthesis of Compounds of Formula I

Compounds of Formula I can be prepared according to the processes described in the following representative Schemes. Reagents and conditions given are only for illustration purposes and alternative methods may be employed by those skilled in the art. It should be understood that the following Schemes do not limit the invention which is defined by the claims. Typically the synthesis of a compound of Formula I includes the following general steps: (1) deprotection of a phosphonate or phosphinate ester; (2) introduction of a phosphonate or phosphinate; (3) formation of the amide bond; (4) preparation of the aryl or heteroaryl carboxylic acid; (5) construction of the aryl or heteroaryl carboxylic ester. The order of introduction of a phosphonate or phosphinate group and the formation of the amide bond in the synthesis of compounds of Formula I can be freely decided by those skilled in the art based on the structure of the substrate. Variable groups in Schemes have the same meanings defined for Formula I unless stated otherwise. In all applicable structures contained in the Schemes described in this invention, P¹ is a protecting group such as C₁₋₄-alkyl; P² is alkyl or cycloalkyl; P³ is a leaving group such as F, Cl, Br, I, or triflate; P⁴ is P³, —P(O)(OP¹)₂, or —P(O)(OP¹)P²; P⁵ is aryl, heteroaryl, alkyl, cycloalkyl, or arylalkyl; X′ is X or a functional group that can be transformed into X; and Y′ is R² or a functional group that can be transformed into R². Protection and deprotection in the Schemes may be carried out according to the procedures generally known in the art (e.g., T. W. Greene and P. G. M. Wuts, “Protecting Groups in Organic Synthesis”, 3^(rd) edition, John Wiley & Sons, 1999).

Deprotection of a Phosphonate or Phosphinate Ester

Compounds of Formula I wherein R⁵⁰ is —P(O)(OH)₂ or —P(O)(OH)P² may be prepared from phosphonate or phosphinate esters using the known cleavage methods. Silyl halides are generally used to cleave various phosphonate or phosphinate esters and give the desired phosphonic or phosphinic acid upon mild hydrolysis of the resulting phosphonate or phosphinate silyl esters. When needed, acid scavengers (e.g., HMDS) can be used for the acid sensitive compounds. Representative conditions can be found in the Generation of phospho(i)nic acid section in this publication. Methods to form phosphonate monoesters can be found in the Generation of Phosphonic Acid Monoesters section in this publication.

Introduction of a Phosphonate or Phosphinate Ester

The introduction of a phosphonate or phosphinate group generally can be accomplished according to known procedures. Compounds of Formula I wherein D is nitrogen-containing heteroarylene may be prepared by a number of known methods (Scheme 2). For example, the coupling reaction of a phenyl bromide (J. Org. Chem. 1999, 64, 120), iodide (Phosphorus Sulfur 1997, 130, 59) or triflate (J. Org. Chem. 2001, 66, 348) with diethyl phosphite or diisopropyl phosphite in the presence of a palladium catalyst is widely used within the art. Alkylphosphinic acid isopropyl ester or alkylphosphinic acid ethyl ester may be used in the aforementioned procedures to afford the desired alkylphosphinate esters. Other methods such as Michaelis-Arbuzov reaction (Chem. Rev. 1981, 81, 415) can also be used to introduce the phosphonate group by coupling a benzyl, arylalkyl, or heteroarylalkyl halide/triflate with triethyl phosphite or triisopropyl phosphite. Lithiated heteroaryl ring carbon can react with dialklyl chlorophosphate to attach the phosphonate group to the corresponding heteroaryl ring.

Formation of an Amide Bond

Standard amide bond formation methods can be used to couple amino groups with carboxylic acids or activated derivatives thereof. For example, (i) reactions of an amine with a carboxylic acid in the presence of DCC or EDC according to the known methods (e.g., J. Org. Chem. 1977, 42, 2019); (ii) conversion of a carboxylic group to an acid chloride by reaction with oxalyl chloride, followed by coupling the acid chloride with an amine in the presence of a base (e.g. triethyl amine or pyridine) in chloroform or DCM (Org. Synth., Collect Vol. V, 1973, 336); (iii) other known procedures (Tetrahedron Lett. 1990, 31, 7119; Tetrahedron Lett. 1989, 30, 6917; J. Org. Chem. 1993, 58, 618).

Preparation of the Aryl or Heteroaryl Carboxylic Acid

Deprotection reactions of carboxylic esters are well known in the art. Methyl or ethyl ester is deprotected in the presence of sodium hydroxide or lithium hydroxide in a mixture of THF/EtOH/water (e.g., Tetrahedron Lett. 1977, 3529). Benzyl ester is removed using hydrogenolysis conditions (e.g., Org. React. 1953, VH, 263).

Reagents and conditions given are only for illustration purposes and alternative methods may be employed by those skilled in the art. It should be understood that the following Schemes do not limit the invention which is defined by the claims. Typically the synthesis of a compound of Formula II includes the following general steps: (1) deprotection of a phosphonate or phosphinate ester; (2) formation of the amide bond; (3) preparation of the aryl or heteroaryl carboxylic acid; (4) construction of the aryl or heteroaryl carboxylic ester; (5) introduction of a phosphonate or phosphinate. The timing of introducing a phosphonate or phosphinate group in the synthesis of compounds of Formula II can be freely decided by those skilled in the art based on the structure of the substrate. Variable groups in Schemes have the same meanings defined for Formula II unless stated otherwise. In all applicable structures contained in the Schemes described in this invention. P¹ is a protecting group such as C₁₋₄-alkyl; P² is alkyl or cycloalkyl; P³ is a leaving group such as F. Cl. Br, I, or triflate; P⁵ is aryl, heteroaryl, alkyl, cycloalkyl, or arylalkyl; X′ is X or a functional group that can be transformed into X; Y″ is R²-R⁵⁰ or a functional group that can be transformed into R²-R⁵⁰; Y¹ is arylene, alkylene, heteroarylene, cycloalkylene, or arylalkylene; Y1′ is Y1-R⁵⁰ or a functional group that can be transformed into Y1-R⁵⁰.

Wuts, “Protecting Groups in Organic Synthesis”, 3^(rd) edition, John Wiley & Sons, 1999).

Deprotection of a Phosphonate or Phosphinate Ester

Compounds of Formula II wherein R⁵⁰ is —P(O)(OH)₂ or —P(O)(OH)P² may be prepared from phosphonate or phosphinate esters using the known cleavage methods. Silyl halides are generally used to cleave various phosphonate or phosphinate esters and give the desired phosphonic or phosphinic acid upon mild hydrolysis of the resulting phosphonate or phosphinate silyl esters. When needed, acid scavengers (e.g., HMDS) can be used for the acid sensitive compounds. Such silyl halides include TMSCl (J.

Example 213 {4-[3-(2-Fluoro-phenylcarbamoyl)-5-isopropoxy-phenoxy]-phenyl}-phosphonic acid

To a solution of 3-[4-(diisopropoxy-phosphoryl)-phenoxy]-5-isopropoxy-benzoic acid (prepared as in Example 3 Step E) (530 mg, 1.2 mmol) in toluene (10 mL) was added thionyl chloride (0.22 mL, 3.0 mmol). The reaction was heated to 110° C. for 1 h and allowed to cool to room temperature.

EXAMPLES Biological Examples

The assays below can be used to test compounds of the present invention. Compounds set forth in the chemistry Examples above were assayed using the Human Enzyme Assay below (compounds may have been tested in additional assays as well). The compounds of the above Examples were tested in the Human Enzyme Assay at a concentration of 100 μM and were able to activate 50 μg of human glucokinase by at least 150%.

Example A Human Enzyme Assay

Biochemical activation of GK is accomplished with assays that utilize purified recombinant human GK (isoform 1/variant 2) and purified recombinant Leuconostoc mesenteroides glucose-6-phosphate dehydrogenase (Sigma-Aldrich, Inc.). In these assays, glucose is acted upon by GK to form glucose-6-phosphate. Subsequently, glucose-6-phosphate is acted upon by glucose-6-phosphate dehydrogenase to form 6-phospho-D-gluconate and beta-NADPH, which can be quantified spectrophotometrically. Specifically, compounds are serially diluted to 100× the final concentration in DMSO. After dilution, 3 uL of the compound solution and 277 uL of Reaction Buffer (25 mM HEPES-pH 7.4, 25 mM KCl, 2 mM MgCl₂, and 10 mM ATP, 0.5 mM beta-NADP, 1 mM DTT, 0.1% bovine serum albumin) are added to each well of a UV/Visible transparent 96-well microtiter plates (Falcon Inc.). The microtiter plates are then placed on wet ice for 10 min. The enzymatic reactions are initiated by the addition of 10 uL glucose-6-phosphate dehydrogenase (˜40 ug/well) and 10 uL of GK (˜50 ug/well). After initiation, the microtiter plate is immediately placed into a microtiter plate reader (SpectraMax 190; Molecular Devices Inc.) and the generation of beta-NADPH is monitored at 340 nm for 20 min at 30° C.

Example B Rat Hepatocyte Assay

Cellular activation of OK is accomplished with assays that utilized [2-³H] glucose (G.E. Healthcare Inc.) and primary hepatocytes isolated from fed adult male Sprague-Dawley rats (Harlan Inc.). All animal procedures are conducted in accordance with the National Institutes of Health Guidelines for the Care and Use of Laboratory Animals and are approved by the Institutional Animal Care and Use Committee. In these assays, [2-³H] glucose is taken up into the hepatocytes and acted upon by endogenous GK to form [2-³H] glucose-6-phoshphate. Subsequently, [2-³H] glucose-6-phoshphate is acted upon by endogenous phosphoglucose isomerase to form fructose-6-phosphate and ³H₃O⁻, which diffuses out of the hepatocyte into the culture media. Specifically, rats (˜300 g) are anaesthetized with pentobarbital (Savemart Inc.) administered at concentration of 2 uL/gram body weight. After confirming no response to deep pain stimuli, the abdominal cavity is exposed. The livers are perfused at ˜25 ml/min through the portal vein with Perfusion Buffer [Krebs-Ringer bicarbonate buffer supplemented with 2.5 mM CaCl₂ and 1% fatty acid free BSA (Calbiochem Inc.)] and drained through the supra vena cava during the procedure. The buffer is prepared by equilibrating at 37° C. and aerating with a 95% oxygen/5% carbon dioxide mixture. After, 2 to 3 min the Perfusion Buffer is supplemented with 1 mg/ml collagenase (Sigma-Aldrich Inc.). Following perfusion viable cells are isolated will 70% Percoll gradient in aerated Perfusion Buffer. After isolation, hepatocytes are resuspended (700,000 cells/mL) in Dulbeeco's minimal essential medium (DMEM, Invitrogen Inc.) supplemented with 5.6 mM glucose, 10% fetal bovine serum (FBS). 1 U/mL penicillin, 0.1 mg/mL streptomycin, and 2 mM L-glutamine. The resuspended hepatocytes are plated 500 uL/well on a 24-well plate (Becton Dickenson Labware Inc.) and incubated at 37° C. in 95% O₂/5% CO₂ in a water-jacketed incubator (Form a Scientific Inc.). After attachment to the plate (˜2 hr), media is removed and 500 uL of serum-free DMEM supplemented with 5.6 mM glucose, 1 penicillin, 0.1 mg/mL streptomycin, and 2 mM L-glutamine is added. After 16-20 hr, 2 uCi/mL [2-³H] glucose and compound solutions are added to the media. Compounds are first serially diluted to 100× the final concentration in DMSO and are added in a 5 uL volume. After 3 hrs, 500 uL of media is removed and ³H₃O⁺ is isolated by strong anion exchange chromatography using AG 1-X8 columns (Bio Rad Laboratories Inc.) according to the manufacture's recommendations. Quantification of the isolated ³H₃O⁺ is accomplished by scintillation counting using scintillation cocktail (Packard BioScience Inc.) and a scintillation counter (LS6000IC; Palo Beckman Inc.).
